Because the style doesn't even draw labels, and for many other objects it  
can't check parenting anyway, plus doing the check every time is somewhat of 
an overhead. So the style has to handle this with event filters installed in 
::polish(), and it either has to walk up the widget tree upto the root for 
every widget that is created checking for toolbar, or do something like this. 
And performance matters, so the name check is there. The reason Liquid 
doesn't need to do this is that it, IIRC, simply uses the stiple to draw the 
background, and so Qt draws it for it. However, changing the background brush 
requires dozens of hacks to get the alignment right.

It certainly works for KAddressBook -- could you perhaps compare what you're 
doing with it?
